How to Know if a Duct Cleaner Did a Thorough Job

How to Know if a Duct Cleaner Did a Thorough JobThe best way to verify the cleanliness of your heating and cooling system is through a visual inspection. However, looking inside of sealed ductwork can present a challenge. Most service technicians use remote cameras so they can view every inch of the system. If they find any visible debris inside the ducts, that would indicate that you need an air duct cleaning. For this reason, it is important to have your ducts regularly inspected by a professional.

Why should you keep your ducts clean?

A thorough cleaning of your ductwork can help improve the efficiency of your HVAC system and improve the air quality in your home.

Checklist for Your Air Duct Cleaning Service Provider

Here is a list of items to go over with your service provider after he completes your air duct cleaning service call.

General Questions

  • Was it possible to clean the entire HVAC system including all the ductwork, drain pans, humidifiers, coils, and fans?
  • Ask him to show you pictures of the cleaned ductwork and plenums (spaces where the air mixes)?

Furnace or Heating System

  • What is the condition of the surface of the heat exchanger?

Cooling System

  • Is the cooling coil visibly clean? (You should be able to shine a flashlight into the coil and see it on the other side)
  • Are the coil fins straight and even? Has there been any damage to the coil?
  • Did the technician verify that the coil drain pan is clean and drains as it should?

Blower

  • Are the blower blades free of oil and debris?
  • Has the blower compartment been cleaned of visible dust or dirt?

Plenums

  • Is the return air plenum free of visible dust or debris?
  • Do the filters fit correctly and are they the proper efficiency as recommended by HVAC system manufacturer?
  • Is the supply air plenum (directly downstream of the air handling unit) free of moisture stains and contaminants?

Metal Ducts

  • Are interior ductwork surfaces free of visible debris?

Fiberglass Components

  • Is all fiberglass material in good condition?

Access Doors

  • Are newly installed access doors in sheet metal ducts attached with more than just duct tape (e.g., screws, rivets, mastic, etc.)?
  • With the system running, is air leakage through access doors or covers very slight or non-existent?

Air Vents

  • Have all the registers, grilles, and diffusers been firmly reattached to the walls, floors, and ceilings?
  • Are the registers, grilles, and diffusers visibly clean?

System Operation

  • Does the system function correctly in both the heating and cooling modes after cleaning?

Your technician should be willing to answer your questions and show you evidence of their work. To ensure you get the best service possible, make sure you contact a reputable service provider.
